Separate the heat sink from the processor by twisting the heat sink
back and forth to loosen the grip of the thermal bonding
compound, then slide the heat sink off to one side of the processor.

Ensure that the securing lever on the ZIF socket is still in the
upright position.
Take the upgrade processor out of its anti-static packaging.
Hold the processor by its edges and avoid touching the metal
pins.
The upgrade processor and the ZIF socket are keyed to ensure
that the processor is installed in the correct orientation. One
corner of the socket has a key hole. The corresponding corner
of the processor is slightly bevelled and has a positioning guide
in the form of a coloured dot.
Place the processor in the socket, making sure that it is
correctly aligned and that you do not bend or otherwise
damage the pins.
If the processor is not big enough to occupy the entire socket it
should be positioned centrally.
Caution
If the processor is misaligned it will not go into the socket, and any
attempt to force it will damage the processor, or the socket, or
both.
Move the securing lever to the locked position. Apply just
enough pressure to overcome the resistance offered by the
lever.
If necessary, place the heat sink into position on top of the new
processor. The vanes of the heat sink must be aligned with the
airflow from the fan in front of the processor. Refit the clip
that secures the heat sink to the processor.
